hat's another post that is here more to be a reminder to me that to be really usefull or add important informations.

Since I am migrating to a new VPS and I'd like to keep my personal stuff separated from the other sites I hosted on my server, I decide to get 2 IP addresses to use.

Then the problem is how to use both of them: well, really simple. The new installation uses Archlinux and the default systemd-networkd, so once I created the file for the interface, I just needed to add another Address = line to it to use the second IP.

The end results is something like:

[Network]
Address=your_first_ip
Address=your_second_ip
Gateway=your_gateway
DNS=your_dns

and just restart. That's all. Really. (I was afraid it would be way more complicated to be honest)
